A possible way to break down Voynich text

[ReneZ]

Statistically some characters cannot be the same because they appear in very different circumstances. l for example appears in completely different environments than y so I really doubt they are the same. But m appears in many of the same places as y and also looks similar to it in the text - and this is something I only realized after trying to figure out what combinations y could join in.

One has to be careful with such considerations, because it can equally be argued that two shapes that appear in completely different environments can represent the same character, and the two forms are to be used in these different environments as a result of some rule.
This happens with 's' for example (special form at end of word), or with 'r' (r rotunda following a round shape).

The two forms of s don't look at all alike, while the two forms of r have some similarity.
